That is the firmware (and hardware revision)
Those come stock and preloaded in every vesc tool
You mentioned you flashed dv4s 5.03 firmware, if so try a normal/recent vesc tool and flash the stock 410/411/412 firmware so you’re on the latest version since you seem to have done the big firmware jump already (from very old to recent)
Remember the precompiled vesc tool archive if you ever need a different version
The recent vesc tools do have a firmware archive pre installed but sometimes the dedicated tool works better in my experience.
